ABSTRACT:
The present invention is an apparatus for cycling a valve having a valve operator for rotationally operating the valve. The apparatus includes a rotary actuator having an output shaft for developing a rotational force and a torque-sensing release clutch for transferring the rotational force to the valve operator. The torque-sensing release clutch decouples the rotational force from the valve operator upon sensing torque at least as great as a preset torque limit. In a preferred embodiment, an adaptive mounting assembly mounts the apparatus to the valve, providing three-dimensional adjustment of the clutch position relative to the valve operator. A counter counts turns of the valve operator to measure and indicate position of the valve, and a switch disables the rotary actuator when the clutch decouples the rotational force from the valve operator.
